PSA Nitrogen ( N2) generator/ plant

Runoff: 1 – 3000 Nm3/ h
Purity: 97 - 99.9995%
Pressure: 0.05 - 1.0Mpa
Dew Point: -60 - -45 oC

Principles:
PSA nitrogen generator uses carbon molecular sieve as sorbent, produces nitrogen by making use of
the PSA principle. Under certain pressure, carbon molecular sieve has different oxygen/ nitrogen
adsorption capacity, i.e. much more oxygen adsorption capacity than nitrogen adsorption capacity.
PLC controls pneumatic valve on/ off to realize two towers alternate adsorption and desorption as per
pressure change, carries out oxygen/ nitrogen separation and produces nitrogen with desired purity.

Applications:
1. Metallurgy: For anneal protection, agglomeration protection, nitrogenizing, furnace washing and
blowing , etc. Used in fields such as metal heating treatment, powder metallurgy, magnetic material,
copper process, metallic mesh, galvanized wire, semiconductor, etc.
2. Chemical and new material industries: For chemical material gas, pipeline blowing, gas replacement, gas protection, product transport, etc. Used in fields such as chemical , urethane elastic fiber, rubber, plastic, tyre, polyurethane, biological technology, intermediate, etc.
3. Electronic industry: For encapsulation, agglomeration, anneal, deoxidization, storage of electronic products. Used in fields such as peak welding, circumfluence welding, crystal, piezoelectricity, electronic porcelain, electronic copper tape, battery, electronic alloy material, etc.
